Electrical connection

Damage to the unit due to a short circuit if water enters the electronics compartment.

  1. Ensure correct, tight line feedthrough through the cable feedthrough and membrane grommet with slot.

Danger of injury due to sharp edges on sheet metal/break-outs in the housing or in the electronics compartment.

Wear protective gloves if necessary. Carefully guide connecting cables into unit. Do not damage cables.

If the connecting cables are too short, the electronic slide-in module cannot be fully pulled out and fitted on the housing. Ensure connection cables of a sufficient length inside the ventilation unit.

A fixed wiring for the mains connection is mandatory. The power cable is already wired inside the unit and led out of the unit.

Take electronic unit with main board out of ventilation unit and attach as described below.

  1. Remove front panel and inner cover → Mounting the ventilation unit on the wall.
